"If you did click to "scan" your machine for problems,
the program will tell you that it supposedly detected 38 threats.
Not true. What it actually did was install a so-called Trojan horse
that's a classic example of rogue antivirus software, also known as
"scareware," a growing menace on the Internet.

"This particular program appears to be designed to convince
people to purchase fake antivirus software -– and will likely
display messages, at random intervals, with information about more
fake problems and demands for money. Mr. Ferguson's initial
analysis shows that the program does not have the ability to "phone
home" to the attacker to get instructions to do anything worse
(like deposit programs designed to steal data from your PC).

"It is unlikely that this attack poses a real threat to Mac or
Linux computers, since the downloads they try to push appear to
work only on Windows machines."
